Why is it convenient to use a graph with only positive points

If there is a situation where negative points cannot apply, it is more convenient to use a graph with only positive points.

Let's take for example: weeks vs number of lawns mowed. Now with this, we cannot have negative amount of weeks and we cannot mow a negative amount of lawns. Therefore, it's the most convenient to use a graph with only positive points.

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
